Abstract：
OBJECTIVE: Evaluate the efficacy of denture cleaners on the adhesion of Candida albicans and their effects on the surface, optical, and mechanical properties of resins for conventional, milled, and 3D-printed denture bases.
METHODS: A total of 240 resin samples were made, 120 for testing Candida albicans adhesion, optical stabilities (ΔE00), roughness (Ra), hydrophilicity (°), surface free energy (Owens-Wendt) and 120 samples for testing Candida albicans adhesion, surface microhardness (Knoop), flexural strength and modulus of elasticity in a three-point test, in which they were divided into 3 groups of denture resin (n = 40) and subdivided into 5 cleaners of dentures (n = 8). Data were evaluated by two-way ANOVA and Tukey\'s test for multiple comparisons (α = 0.05).
RESULTS: Denture cleaners with an alkaline solution and dilute acid composition were those that showed the greatest effectiveness in reducing Candida albicans (P < 0.001), however 1% NaOCl significantly affected the properties of the resins (P < 0.05). Denture 3D-printed showed that the surface microhardness was significantly lower for all cleansers (P < 0.05).
CONCLUSIONS: Listerine demonstrated superior efficacy in reducing Candida albicans with minimal effect on denture properties, whereas 1% NaOCl had a significant negative impact on the properties. The mechanical properties were significantly lower in 3D-printed resin than in other resins for all denture cleansers.
CONCLUSIONS: Denture base materials are being sold to adapt to the CAD/CAM system, increasing the number of users of dentures manufactured with this system. Despite this, there is little investigation into denture cleaners regarding the adhesion capacity of microorganisms and the optical, surface and mechanical properties of dentures, thus requiring further investigation.

摘要：
目的：评估义齿清洁剂对白色念珠菌粘附的功效及其对表面的影响，光学，和常规树脂的机械性能，碾磨,和3D打印义齿基托。
方法：共制备了240个树脂样品，120用于测试白色念珠菌的附着力，光学稳定性（ΔE00），粗糙度（Ra），亲水性(°),表面自由能(Owens-Wendt)和120个用于测试白色念珠菌粘附的样品，表面显微硬度（努普），三点试验中的弯曲强度和弹性模量，其中将它们分为3组假牙树脂（n=40）和5组假牙清洁剂（n=8）。数据通过双向方差分析和Tukey检验进行多重比较(α=0.05)。
结果：使用碱性溶液和稀酸成分的义齿清洁剂在减少白色念珠菌方面表现出最大的效果（P<0.001），然而1%NaOCl显著影响树脂的性能(P<0.05)。3D打印义齿显示，所有清洁剂的表面显微硬度均显着降低（P<0.05）。
结论：李斯特林在减少白色念珠菌方面表现出优异的疗效，对义齿性能的影响最小，而1%NaOCl对性能有显著的负面影响。对于所有义齿清洁剂，3D打印树脂的机械性能明显低于其他树脂。
结论：正在出售义齿基托材料以适应CAD/CAM系统，增加使用该系统制造的假牙的用户数量。尽管如此,关于微生物的粘附能力和光学，假牙的表面和机械性能，因此需要进一步调查。
